Magnopus is seeking a Senior Graphics Engineer to help build, scale, and optimise our OKO Unreal Engine plugin and studio-facing Unreal pipelines in the UK.
Working primarily on OKO, our real-time, cross-reality collaboration platform, while also supporting Unreal development across our Studio projects, you'll play a central role in shaping the rendering fidelity and creator workflows that define the experiences we create.
You'll join an established, talented team as a senior Unreal engineer, providing technical leadership across the discipline in a hands-on engineering role.

Own key graphics initiatives across the platform, including asset compatibility, lighting, shader and material workflows, and emerging rendering techniques.
Design and build solutions for runtime asset translation and cross-platform content workflows.
Design, extend, and implement custom Unreal Editor tools, UI extensions, and automated asset pipelines to accelerate content creation.
Tackle low-level graphics, optimisation, and profiling challenges to improve rendering performance and visual fidelity across a range of target hardware.
Set the technical bar for the Unreal team through architecture decisions, robust C++ code, and active code reviews.
Work directly with the teams building OKO's other clients (web, mobile) and cloud services to ensure the Unreal experience is world-class.
Help raise the overall capability of the team through knowledge sharing, documentation, and technical guidance.

Significant professional experience developing in C++ within Unreal Engine, with a deep understanding of the engine's codebase and runtime systems.
Strong graphics and rendering programming foundations, with hands-on experience working within Unreal's rendering code (including the RHI), shader development, and GPU performance profiling.
Experience building, maintaining, or extending Unreal Editor tools, workflows, or pipelines that other developers or artists have relied on.
Strong communication skills and the ability to explain complex technical rendering or tooling challenges to both technical and non-technical stakeholders.
A collaborative mindset and a genuine interest in mentoring peer developers and sharing knowledge across disciplines.
A track record of creating clarity and driving technical progress within a fast-moving product environment.
